gin05-gorm读取数据库返回查询结果到HTML

&emsp;&emsp; go语言有一点逻辑还是合PHP的有一点不一样的，特别是gorm包一些简单的逻辑，初次使用的时候可能会需要自己弯弯绕绕想明白理解一下。下面是一个简单的示例

main.go

```
package main

//引用包文件
import (
	"gin/app/model"
	"github.com/gin-gonic/gin"
	"net/http"
)

type Content struct {
	//gorm.Model
	Id int `gorm:"type:int;not null",json:"id"`
	Title string `gorm:"type:varchar(200);not null",json:"title"`
	Description string `gorm:"type:varchar(1000);not null",json:"description"`
	Keywords string `gorm:"type:varchar(200);not null",json:"keywords"`
	Thumbnail string `gorm:"type:varchar(200);not null",json:"thumbnail"`
	ModelId int `gorm:"type:int(11);",json:"model_id"`
	TitleStyle string `gorm:"type:varchar(100);",json:"title_style"`
	CateId int `gorm:"type:int(10);",json:"cate_id"`
	RelHits int `gorm:"type:int(10);",json:"rel_hits"`
	Hits int `gorm:"type:int(10);",json:"hits"`
	Ordid int `gorm:"type:int(10);",json:"ordid"`
	AddTime int `gorm:"type:int(12);",json:"add_time"`
	LastTime int `gorm:"type:int(12);",json:"last_time"`
	Status int `gorm:"type:int(12);",json:"status"`
	Top int `gorm:"type:int(12);",json:"top"`
	HiddenInfo string `gorm:"type:varchar(1000);",json:"hidden_info"`
	Score string `gorm:"type:varchar(1000);",json:"score"`
	Recommend int `gorm:"type:int(10);",json:"recommend"`
	Comment string `gorm:"type:varchar(1000);",json:"comment"`
	Uid int `gorm:"type:int(10);",json:"uid"`
	Like int `gorm:"type:int(10);",json:"like"`
	Unlike int `gorm:"type:int(10);",json:"unlike"`
	Index int `gorm:"type:int(10);",json:"index"`
	Baijiahao int `gorm:"type:int(10);",json:"baijiahao"`
	IsMd int `gorm:"type:int(10);",json:"is_md"`
	From string `gorm:"type:varchar(100);",json:"from"`
	Fav int `gorm:"type:int(10);",json:"fav"`
	Imgs string `gorm:"type:json;",json:"imgs"`
	Pid int `gorm:"type:int(10);",json:"pid"`
	AllowComment int `gorm:"type:int(10);",json:"allow_comment"`
	//DeleteTime int `gorm:"column:delete_at",json:"delete_at"` // 将列名设为
	//DeleteTime gorm.DeletedAt `gorm:"type:int(11);",json:"delete_time"`
	//DeletedTime *time.Time `sql:"index" json:"delete_time"`
}

func (Content) TableName() string {
	//config ,err := ini.Load("config/db.ini")
	//if err != nil {
	//	fmt.Println("配置文件读取错误，请检查文件路径:", err)
	//}
	//
	//prefix := config.Section("database").Key("DbPrefix").MustString("zhe_")
	//绑定MYSQL表名为users
	//return prefix+"content"
	return "zhe_content"
}

func main() {
	router := gin.Default()

router.LoadHTMLGlob("templates/**/*")
	//router.LoadHTMLFiles("templates/template1.html", "templates/template2.html")

router.GET("/index", func(c *gin.Context) {
		c.HTML(http.StatusOK, "index/index.html", gin.H{
			"title": "Main website",
		})
	})

router.GET("/test/:id", model.ContentGetArticle)

// 此 handler 将匹配 /user/john 但不会匹配 /user/ 或者 /user
	router.GET("/read/:id", func(c *gin.Context) {
		id := c.Param("id")
		c.HTML(http.StatusOK, "article/article.html", gin.H{
			"id": id,
		})
	})
	router.Run(":8001")
}

```

Content.go

```
package model

import (
	"fmt"
	"github.com/gin-gonic/gin"
	"gorm.io/driver/mysql"
	"gorm.io/gorm"
)

func ContentGetArticle(c *gin.Context)  {
	dsn := "root:123456@tcp(127.0.0.1:3306)/micuer20220812?charset=utf8mb4&parseTime=True&loc=Local"
	db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})
	if err != nil {
		fmt.Println("链接数据库错误", err)
	}

id := c.Param("id")
	name := c.Query("name")

content := Content{}

db.Debug().Where("id = ?",id).Find(&content)

fmt.Println("查询")
	fmt.Println(content)
	fmt.Println(id)
	fmt.Println("res数据")

//c.JSON(200,gin.H{
	//	"res":content,
	//	"name":name,
	//})

c.HTML(200,"article/article.html",gin.H{
		"res":content,
		"name":name,
	})
	//c.HTML(200,"article/article.html", gin.H{
	//	"res": content,
	//})
}
```
 article.html
 
```
{{ define "article/article.html" }}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>{{.id}} - 文章详情</title>
</head>
<body>
<h1>现在是文章详情，为啥显示成了json</h1>
{{.id}}

<h2>
    {{.res.Id}} - {{.res.Title}}
</h2>

<h2>
    name {{.name}}
</h2>
</body>
</html>
{{ end }}
```
